Abstract
An object is tracked with a plurality of cameras, at least one of which is sensitive to both visible and invisible light. An invisible light illuminator attached to the object reflects a target of invisible light. At least one camera processes the invisible light. A command module then selects and activates one of the cameras based on the satisfaction of a triggering condition, which may be based upon appearance, proximity, orientation, position, or any other characteristic of the illuminator with respect to the cameras.
